DIE FOR EMBOQSING AND CUTTING WALL-PAPER.

Specification of Letters Patent. Patented 24, 1914.

Application filed November 16, 1912. Serial No. 731,664

To all whom-it may concern:

Be it known that I, HENRY Boson, a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Dies for Embossing and Cutting all-Paper, ofwhich the following is a specification.

My invention relates to certain new and useful improvements in dies for embossing scribed and explained in the specification and shown in the accompanying drawings, in which:

Figure 1 is a section on the line 1 of Fig. 2, that is, a vertical transverse section, and Fig. 2 is a horizontal section on the planes indicated by the line 2 of- Fig. 1.

The present invention is adapted'to be used in connection with the apparatus of my Patent No. 1,057,703, dated April 1st, 1913, on a machine for cutting wall-paper. In that machine, I illustrate paper feeding and reeling means which is adapted to carry a wall-paper with an irregular border between dies in a die-press, the purpose of the dies being to cut out the irregular edge of the paper. along the margin of the previously-printed pattern thereon. machine, the construction of the die is notof importance and it and the die-press may, subject to the limitations therein pointed out, be ofany desired form. In the present case, I have devised a die which not only does the work performed by the die illustrated in that machine. but which as well embosses the paper so that, by a single operation, the wall-paper, when properly positioned, has its pattern embossed and its edge substantially severed. The means illustrated in that machine may, if desired, be applied to the present die and it is my intention that it shall be so applied in practice, but since there is no necessary combination between the two constructions, it is not proper to speak of the present invention as an improvement upon the machine of the above-mentioned patent.

Referring to the drawings, 3 isthe member normally reciprocated in any die-press by the operation of its moving parts, said member being supported by a cross-head 4 which is reciprocated in an ordinary way through. an eccentric mechanism as on a shaft 5, whose rotation can be controlled by a clutch-mechanism diagrammatically i1lus- In thatv trated at 6. This of course, difiers in no material way-from any ordinary die-press and the parts are enumerated merely for clearness of understanding.

Beneath the member 3' is a heating-box 7 which is maintained at a comparativelyhigh temperature by any suitable means. Preferably, I burn within said box gas or a hydrocarbon vapor which issues from a burner-tube 8, or a plurality thereof, as may be required. A detailed description of this heating means is not believed to be necessary for the reason that interior heating means for hollow metal receptacles are well i known in the art.-

Beneath the heating-box 7 is an upper die 9, the surface of which is so formed as to produce the necessary corrugations or embossing of the wall-paper to be treated and the edges of which are irregularlv cut to conform to the irregular margins desired. Beneath the upper die 9 is 'a lower die 10 with correspondingly-shaped margins and with a surface which is the counterpart of the upper-die. The lower. die 10 is mounted on posts 11 which are supported and vertically movable in holes in a guiding-plate 12.

'Beneath the guide-plate 12 is a Presser-plate 13 supported upon spring-members 14 which, in the present instance, are made in theform of soft rubber cylinders surrounding bolts 15 screwed into the guide-plate 12.

Above the guide-plate 12 arelower marginal dies 16, which are counterparts of the edges of the upper and lower dies heretofore men- .tioned.

The purpose and operation of the present construction can now bereadily understood. It has been found, in practice, that to secure proper embossing it is desirable to maintain a heavy pressure for a considerable period and, to avoid tearing or rupturing the fabric, it is desirable that the pressure gradually increase rather than he suddenly and swiftly applied. However, the principal point is that a heavy pressure shall be maintained long enough for the heat in the upper die to be effective in setting the embossing. The paper to be treated is, there fore, fed between the upper and lower dies -9 and 10, the upper of which is hot, and

when the paper is so positioned longitudinally that its previously-printed pattern will register with the proper points in the dies, the upper die is brought down through the ordinary mechanism of the die-press.

The press, is, of course, moving somewhat slowly when the up er die reaches the paper so that the firstaction of the embossing dies is slow. As the upper die continues to descend, the pressure upon the paper increases and both dies move down together, depressing thepresser-plate 13 against the force of which the upper die rises therefrom, so as to release the paper and the die-press stops. The paper is thenmoved along by suitable feeding means one step or figure of the pattern and the operation is repeated.

I realize that considerable variation is possible in the details of the present construction, without departing from the spirit of my invention and, by having described the same in detail, I do not intend to be limited thereto, except as pointed out in the following claims, in which it is my intention to set forth all .the novelty inherent in the construction described as broadly as may be permitted by the state of the art.

\Vhat I-claim as new and desire to secure by Letters Patent is: 1

1. In combination, a die-member having an embossing surface and cutting edge, an elastically supported counterpart die having a correspondingly shaped edge, a cutting die having an edge which is the counterpart of the edges of the first mentioned dies, and means for reciprocating one of said embossing dies into operative contact with the other and then into engagement with the cutting die.

2. In. combination, a die-member having an embossing surface and cutting edge, an elastically supported counterpart die having a correspondingly shaped edge, means for heating one of said embossin dies, a

cutting die having an.- edge which is the counterpart of the edges of the first mentioned dies, and means for reciprocating one of said embossing dies into operative contact with the other and then into engagement with the cutting die.

embossing dies and mounted in vertical" alinement with the edges of said embossing dies, and means for reciprocating one of said embossing dies into operative contact with the other and then into engagement with the cutting die.

In testimony whereof I have hereunto set my hand this 14th day of November, A. D.

I HENRY BOSCH.
